Dear @JongHoon-Jeong, You mention that you are changing the wind and wave directions between simulations. Can you clarify what exactly you are changing in your input files between each case? When you change the wind direction, are you also changing the nacelle-yaw angle to align the rotor with the wind? FYI: In the input files you shared, the wind direction in the InflowWind input file is 75 degrees ( Best regards, |

When changing the wind direction, I am modifying the PropagationDir parameter in the InflowWind module, and when changing the wave direction, I am modifying the WaveDir parameter in the Seastate module. |

Dear @JongHoon-Jeong, For changing the wave direction, you should only need to change For the jacket model, potential flow is not used so the setting of With a 180degree change in wave direction and no second-order mean-drift effects enabled, I would expect small changes in the phase of the wave forces, but not as obvious as say a 90degree change in wave direction.

As you mentioned, there was a noticeable change in the phase of the wave forces when WaveDir = 90 degrees, but the response at WaveDir = 180 degrees was still almost identical to the response at WaveDir = 0 degrees. I am not quite sure why the response at WaveDir = 0 degrees and the response at WaveDir = 180 degrees are almost the same when second-order mean drift effects are not considered. Could you possibly explain this from a theoretical perspective? Thank you. |

Dear @JongHoon-Jeong, For the same spatial-temporal discretization and random seeds, the wave-elevation time series at (X,Y) = (0,0) is identical in OpenFAST regardless of the wave direction. The wave direction will change how the wave-elevation at (0,0) gets propagated to other (X,Y) locations, but this may not be that important for structures with limited (X,Y) extent. The wave direction will also change the wave particle velocity and acceleration components, but for a 180-degree change in wave direction, this will only flip the signs on the horizontal components, with the vertical components will be unchanged at (0,0).

I am currently studying the OpenFAST fixed-bottom offshore wind turbine example file '5MW_OC4Jckt_DLL_WTurb_WavesIrr_MGrowth'.
I varied the wind direction and wave direction and generated approximately 1-hour time histories of TwHtFLzt, TwHtMLxt, TwHtMLyt, and TwHtMLzt, displayed as shown in the figure below.
Here, TwHt1 refers to the bottom of the tower, TwHt2 refers to the mid-point of the tower, and TwHt3 refers to the top of the tower.
However, I find it strange that the three cases show nearly identical results for all four responses. I would expect the responses to differ noticeably as the wind and wave directions change, but I cannot understand why the results are coming out this way.
I have listed the input files I configured for this example below.
